CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 446,571, dated February17, 1891..

Application filed October '7, 1890. Serial No. 367,319. (No model.)

To all whom it may concern:

Be it known that I, JOHN PLAYER, a citizen of the United States,residing at Topeka,

Shawnee county, Kansas, have invented a new and useful Improvement inGar-\Vheels, of which the following is a specification.

Cast-iron car-wheels are heavy and easily broken, and pressed-steelwheels such as have heretofore been used to obviate these defects areliable to wear out or bend in the tread. To prevent this is the objectof my invention, and this object I accomplish by thickening the tread ofthe wheel, as hereinafter set forth.

In the drawings, Figure 1 is a central vertical section of the blankused to form part of the wheel; Fig. 2, a similar section of thecompleted wheel, taken on line 2 2 of Fig. 3, looking in the directionof the arrows; Fig. 3, an elevation of the left side of the wheel shownin Fig. 2, and Fig. 4 an elevation of the right side thereof.

A is one part of the wheel; B, the-other; C C,the parts of the hub; D,the bolts that hold the hub together, and E a plate or disk.

In constructing my improved wheel, the part A is first made in the formof a circular steel or wrought-iron blank of suitable dim ensions, asshown in Fig. 1. It is provided with openings a, projections a", and anannular thickened portion a. the blank is so placed as to form the treadof the wheel when complete. The blank is further provided with suitableholes to allow the hub and fastening-bolts to pass through it. The blankis then bent in a press or by other suitable means into the form shownin Fig. 2, the thickened-part a being bent to form the tread and thatpart of the blank lying outside of this portion being bent to form ashoulder F. A circular steel or wrought-iron disk 13 is then made andplaced inside the part A, rest- This thickened part of ing against theshoulder F. The points a at first stand at a proper angle to admit thedisk and are then bent over upon it, as shown in Figs. 2 and 4:, therebylocking the partsof the wheel together and holding the disk firmly inplace.

The hub is made preferably in three parts, a flanged sleeve Oand twoflanged collars 0', all fitting together, as shown, and held in place byrods or bolts D passing through the two parts of the wheel and theflanges on the col.

lars C, and riveted, as shown. A supplemental disk E may be used, ifdesired, to aid in supporting the tread and to add strength to thewheel; but this is not an essential part of my invention, whichprincipally consists in thickening the tread of the wheel, as shown.

As will be obvious, a wheel thus made will be strong and durable, notbending or easily wearing through in the tread. The tread is supported,asshown, by means of its attachment to the disk B by the concave side ofthe part A, and also by the supplemental disk when that is used.

I claim- 1. In a car-wheel the combination of a part A, having athickened portion a, forming the tread of the wheel, and a disk 13,secured thereto, substantially as described.

2. A car-wheel comprising a part A, having a thickened portion a,forming the tread of the wheel, a disk B, secured therein, and a hub OC, substantially as described. 3. A car-wheel comprising the part A, having a thickened portion a, forming the tread of the wheel, the disk B,secured thereto, a hub C C, and a supplemental strengtheningdisk E,substantially as described.
